Here it depends on the inflection of your voice. "Excuse me" could mean you were getting ready to walk past someone or reach over them (like in the grocery store) to pick something up and didn't want them to be startled, or if you wanted to ask someone a question, you might preface it with "Excuse me." Also depending on the tone of your voice, it might indicate you didn't like what someone said and replied sternly, "Excuse me?"Excuse me is a common way to approach others here but if you said excuse me to mean pardon? Then it would have the same inferred “What did you just say?!!” thing as “I beg your pardon”
